Due to the fast growth of building construction technology and increasing demands on the efficient use of land, human living space are expanded from on the surface to above and under the earth surface. It raises the need for three dimentional (3D) cadastral by realizing that the current cadastral system based on 2D is not appropriate to reflect...

This paper presents a novel approach for eliminating speckle noises in Laser Doppler Vibrometer signals based on empirical wavelet transform (EWT). The moving root-mean-square thresholds are utilized to cut off signal drop-outs and produce noise discontinuity that EWT can identify. The extremum ratio behaves as the criterion to reject or accept...

Laser Doppler Vibrometer (LDV) is extensively applied in remote and precise vibration measurements for structural monitoring. Speckle noise is a severe signal issue restricting LDV applications, mainly when an LDV scans from moving platforms. Realistic simulations and thorough characterizations of speckle noise can support the despeckle...

We propose two strategies for eliminating the speckle noise in a laser Doppler vibrometer according to Fourier analysis. Fourier transform is theoretically conducted on the speckle pattern phases, whose variation dominantly contributes to the speckle noise. The calculated and experimental frequency spectra of speckle noise both present...

In recent years, more and more construction enterprises are expanding into overseas markets, especially in underdeveloped regions such as Africa. Compared to domestic construction projects, international construction projects have been faced with more uncertainties and increased levels of safety risks to the employees in the context of political...

In the context of skyrocketing house prices and fierce competition for talents between cities, this study explores the housing pathways of young talents and their future migration plans in Shenzhen, China. Using the housing pathways approach and Bourdieu’s theory of practice with three concepts, this study uncovers how structural factors and...

As the durability and stability of structures in operation are required, effective technologies are necessary to monitor the structural health. Laser Doppler vibrometer (LDV) is a non-contact and non-destructive vibration detector suitable for acquire broadband signals remotely and continuously. The significant signal issue is speckle noise...

In recent years, Chinese housing policies have been shifting from encouraging homeownership toward developing the private rented sector, especially in the superstar cities. Nevertheless, what are the target groups and characteristics of private rental housing in Chinese superstar cities, and whether the private rental housing is capable of...

Inorganic 2D layered CsPbI<sub>3</sub> is awaiting to overcome the phase instability of traditional 3D components. However, the most reported Ruddlesden–Popper (RP) phase 2D CsPbI<sub>3</sub> leads to larger interlayer distance and weaker interlayer coupling since the existence of the van der Waals gap, which deteriorates the performance of...

Two-dimensional (2D) Dion-Jacobson (D-J)-type cesium lead iodide CsPbI <sub>3</sub> perform remarkably in terms of stability. However, the complex interactions between spacer and inorganic layers limit its excellent progress in perovskite solar cells (PSCs). Herein, starting from the considerable structural diversity of organic spacers, we...

In recent years, China has witnessed fierce competition for talents among cities. There is evidence that China's first-tier cities are losing their appeal for young talents due to the soaring housing prices and high living costs in first-tier cities, as well as the catch-up of next-tier cities. Therefore, uncovering what factors drive young...

Last spring, super dust storms reappeared in East Asia after being absent for one and a half decades. The event caused enormous losses in both Mongolia and China. Accurate simulation of such super sandstorms is valuable for the quantification of health damage, aviation risks, and profound impacts on the Earth system, but also to reveal the...

Interface engineering is a simple and effective strategy for improving the photovoltaic performance and stability of perovskite solar cells (PSCs). Herein, an interface co-modification strategy is proposed, using [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and 2-fluoro-1,4-phenylenediammonium iodide (2FPPD) to modify the electron...

Statistical methods, particularly machine learning models, have gained significant popularity in air quality predictions. These prediction models are commonly trained using the historical measurement datasets independently collected at the environmental monitoring stations and their operational forecasts in advance using inputs of the real-time...

This paper presents the work on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. These specimens, representative of sub-structure level components, are used to investigate post-buckling and failure in aerospace structures. Two specimens...

Robust spin-photon interfaces in solids are essential components in quantum networking and sensing technologies. Ideally, these interfaces combine a long-lived spin memory, coherent optical transitions, fast and high-fidelity spin manipulation, and straightforward device integration and scaling. The tin-vacancy center (SnV) in diamond is a...

Empirical mode decomposition (EMD) lacks a strong theoretical support although extensively applied. We propose a theoretical framework for a succinct EMD in this work, with the assumption of invariant extrema locations for one IMF extraction. We define the envelope mean filter (EMF) and prove that the filter matrix satisfies five properties....

The recent revival of the private rented sector in many regions highlights the importance of understanding the well-being of private renters. While there is a consensus that private renters are less satisfied with their life than homeowners, little attention has been given to examining the life satisfaction of private renters from different...

Iodine vacancies and uncoordinated iodide ions of CsPbI<sub>3</sub> films are mainly responsible for nonradiative recombination. Here, we report a composition-engineering passivation method that through guanidium (GA<sup>+</sup>) and I<sup>−</sup> forms strong hydrogen bonds to passivate iodine vacancies and reduce defects. Both experimental...
